ToaZZ whom it may concern I Be it known that I, MAUnIouJ. SOHLESS,

invented certain new and useful Improvements in NecktieClasps, ofwhichthe following is a specification.

My invention relates to an improved form of clasp and has more especial.reference to what are f commonly termed neck tie clasps. In theconstruction of such clasps,

it has heretofore been found difficult to so form and position thespring which is usually interposed between the jaws or shells of theclasps as to cause the gripping teeth formed at one end of the shells toproperly engage or miter.

One object of my invention is to provide a construction wherein theshells or jaws of a clasp will be so acted upon by the spring interposedtherebetween that the teeth which are used to grip the articles to beheld in position will exactly miter. I

It has also, heretofore, been found impracticable to use light metalstock for such tie clasps, as the form of spring generally employed hada tendency to buckle or distort the metal, by reason of the fact thatthe spring. exerted its pressure against one part of the metal and notagainst the other.

Another and very important object of my invention is to provide a formof spring by means of which the pressure exerted thereby against thejaws will be so balanced or proportioned that no part of the jaw underthe influence of the spring will be subjected to any greater pressurethan any other part of the jaw. In this manner any tendency which thespring might have to buckle, bulge or distort the metal is obviated, andI am enabled to use relatively light stock without incurring any risk ofthe same being distorted. p I

. A further object of the invention is to provide a novel form of pivotor stud about which said jaws are pivotally movable.

Other objects of the invention and advantages thereof, as well as theconstruction and operation of the same will be clearly disclosed in thefollowing specification, reference being made to the accompanying draw-Figure 1 1s a perspective view of a clasp embodying the lnvention; Fig.2 1s a top NEGKTIE-CLASP.

plan view with the upper jaw member re moved. Fig. 3 is a plan view ofthe preferred form of spring employed; and Fig.

tis a plan view of a pivot or stud upon which the jaws are mounted.

The invention has been shown as embodied in a neck tie clasp comprisinga pair of suitor shell and having therein a bore lt-designed to receivethe ends of a pintle or stud which is preferably clenched or riveted inposition. x

One of the features of my invention relates to the form of the pivot orstud and I prefer to make the same so that the body portion is ofgreater diameter than the end portions which engage the ears of thejaws. The preferred form of the stud is shown in Fig. 4: from which itwill be noted that the body portion 15 is formed of a hollow wire ortube through which a wire 16 is drawn centrally and axially of the tube15, the ends 16 of the wire projecting beyondthe body 15 and forming thebearings about which the jaws rock.

Another feature of the invention relates to the formation andpositioning of the spring which is interposed between the jaws and actsto force the ends of the jaws which are provided with the teeth 11 and12 toward each other. Before the spring itself is operatively mountedinthe clasp it has the general appearance indicated by Fig. 3. It

will be noted that the spring comprises a substantially elliptical bodyportion 17, intermediate coils 18, and projecting arms 19 which areformed by the termini of the spring. hen in position in the clasp, thecoils 18 encircle the pivot 15, the elliptical portion 17 of the springrests as shown against the inner face of one of the aws, for

example the upper jaw 10, and the termini or arms 19 are juxtaposed andabut or rest against the inner face of the opposite jaw for example thelower jaw 10. Each jaw is but is also of such character as to keep thejaws in exact alinement with each other during operation and while thejaws are at rest. By forming the spring members 17 and 19 as shown inthedrawing, Iobtain equal or uniform, or what may be termed balancedpressure against opposite edges of'each jaw member 10 and by reason ofsuch uniformity of pressure there. is no tendency to buckle or in anymanner distort the metal of the shell at the parts which are subject tothe action of said spring.

The operation of the device is very simple and may be briefly describedas follows Assuming the several parts of the device to be assembled in acomplete clasp as shown in Fig. 1, the body'portion 17 and the arms ortermini 19 will exert their force against the opposite jaws 10 wherebythe teeth formed on the front of the jaws will be caused to engage andexactly miter as shown. When it is desired to clasp an article betweenthe teeth pressure is exerted upon the portions 10 of the jaws thusforcing these parts of the j aws toward each other against the tensionof the spring members 17 and 19. When the pressure is relieved, thespring members just referred to will act to force I a right angle to theplane of the jaw, perforated ears formed on each jaw, apintle upon whichsaid jaws are pivoted, said pintle comprising a tube having a wirepassing therethrough with the ends of the wire projecting beyond thetube and passing through the perforations in the ears, and a springhaving a normal tendency to force the forward ends of the jaws intoengagementwith each other, said spring comprising an integral strand ofwire formed into a continuous curved portion engaging one of the jawsadjacent the flange thereof, two intermediate spaced coils encirclingthe pintle near its oppositeends, and curved arms engaging the other jawmember, each of said arms consisting of a strand extending from theinner end of one of the coils, each of said strands extending along theinner face of the jaw near its central line and being curved to extendin the opposite direction adjacent to the flange of said aw andterminating immediately adjacent the-other end of the coil.

In testimony whereof I have aflixed by signature in presence of twowitnesses.
